To all whom t may concern: Y

Be it known that I, FREDERICK S. GLINEs, a citizen of the United States, residing at L nn, in the county of Essex and State of assachusetts, have invented a new and u seful Improvement in Machines for Applying Adhesive, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for applyingadhesive and `more es ecially to a machine of that character whic is designed to apply an adhesive in spots.

One object of my invention-is to provide a machine for applying adhesive which is efficient, rapid and clean.

Another object is to provide a machine which is small, compact and cheap in construction and simple and effective in operation.

Still another object is to provide means whereby the working arts of my machine ma be readily cleanen ther objects will be in nart obvious and in art pointed out hereina ter.

n the accompanying drawings wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a front elevation, with arts broken away, of a machine constructe and o erated in accordance with my invention; ig. 2 is a plan view of said machine; Fig. 3 is a section taken along line 3 3 in Fig. 2 looking from left to right; and Fig. 4 is an illustration of a piece of material, in this case part of a shoe lining, to which adhesive has been applied in accordance with my invention.

Referring now more particularly to the drawings which illustrate the preferred embodiment of my invention, there is indicated at 10 a base upon which is mounted a lreservoir 11, restrained against lateral movement by lugs 12, adapted to contain a supply of paste or other adhesive, and which is provided with a cover 13 extending over the greater portion of the top of the reservoir.

Said cover may also serve as a table or support for the material to which the adhesive is to be applied. At 14 is shown a spring catch secured to the cover 13 and adapted to frictionally engage one wall of the reservoir for the purpose of retaining said cover in operative position.

One corner of the base 10 is extended and carries a pair of upstandin r ears or lugs 15, each of which has threade therein a conepomted screw 16 which is checked against loosening by a lock-nut 17. At 18 there is a bearing having seats adapted to engage the cone-points of the screws 16 forming a supporting bearin locating art 18 with reference to the ot er pai ts o my machine and allowing said part to be revolvedv about an axis passin through screws 16 for a urpose to be escribed later. Cast on the ase 10 is an upwardly extending ear or lug 19 having a hole adapted to receive a pin 20, which may be passed through two corresponding holes in opposite sides of the part 18 in order to firmly lock the bearing piece in o erative position.

ounted for rotation in the bearing piece 18 are two substantially parallel shafts 21 and 22. Shaft 22 extends to the left and within the reservoir 11 as shown in Fig. 1. Mounted in said shaft are a number of paste applying members -23 (see Fig. 3), comprising a disk or circular plate having radially projecting arms or fingers 24 arranged at suitable intervals about its periphery. Collars 25 serve to separate the paste applying members which, together with the collars are firmly retained on the shaft 22 by a washer 26 and a screw or nut 27 or other suitable means. The disks carrying the fingers are preferably arranged so that the fingers 24 are in a staggered relation.

While I have represented the paste applying element of my machine as being made up of disks and collars, it is to be understood that said element is not limited to the particular construction shown but may be constructed in any suitable manner, as, for instance, a drum having suitable pins inserted therein, or may even be made from one solid piece.

Referring to'the shaft 21, which is substantially parallel to shaft 22, there is mounted on said shaft 21 a series of disks 28, of suitable form, for frictionally engaging and feeding the material to which the paste is to be applied. Said disks are separated or spaced by collars 29 and the disks and collars are firmly retained upon the shaft 21 by a washer 30 and screw or nut 31 or other suitable means. The edges of the disks 28 may be serrated or coated with any suitable material toy increase the friction with which they engage the material to which adhesive is to be applied. 0n the bearing piece 18 and secured thereto by means of screws 32, is shown a piece 33 extending substantially parallel to shaft 2l and adjacent to the feeding disks 28 in such a manner as to form a guard about said disks.

Adjacent the right-hand en d of the bearing piece 18, as shown Fig. 1, are two gears 34 and 35 respectively fastened to shafts 21 and 22. Adjacent gear 34 is shown a pair of grooved pulleys 36 and 37, of which 36 is an idler loose upon the main shaft 21, and 37 is secured to said shaft to transmit power to the shaft 21 and through the gears 34 and 35 to shaft 22. The idler is retained in its position on shaft 2l by washer 38 and screw 39 or other suitable means. j

In Fig. 3 at 40 is shown a bar having fastened thereon at suitable intervals, projecting fingers 41, which are arranged between the paste applying members, as shown in Figs. 2 and 3, to form a guard which acts to prevent the material from becoming entangled with tlie various parts of the mechanism after the adhesive has been applied, and also serves to assist in the separation of the material from the paste applying liners. g Fig. 4 is an illustration of part of a shoe lining 42 as it appears after having the adhesive 43 applied to it by my machine. It is to be understood that the size, shape and arrangement of the spots of adhesive is not limited to that shown in the illustration.

In the operation of my machine, assuming that the reservoir contains a proper amount of adhesive, that the part-s are thoroughly clean and that power has been applied to the pulley 37, the material to which it isdesired to apply the adhesive is placed upn the cover 13 and moved thereon toward the paste applying and feeding elements; when the material comes into engagement with said elements, the feeding disks act upon the material to feed it forward, and, at the same time, to hold it in contact with the paste applying lingers 24 which in their revolution, transfer the adhesive from the reservoir to the material in spots. The material as it emerges from between the feeding and pasting means passes over the guard fingers 41 and is delivered ready for use.

It is possible to use my machine in such a manner as to apply adhesive to a portion of the surface only. It will be noticed that on the left hand side of the illustrated embodiment of my invention, referring to Fig. 1, there is no obstruction to prevent the material from extending outwardly to the left from between the' ',feeding disks and the paste applying fingers. This is an advantage because it enables the operator to so ar- Lemmi i'ange the work that only a portion will be coated, the uncoated portion extending 'to the left from between the feeding disks and the paste applying fingers. By retaining hold of the material the operator can direct its course through the machine in a straight line and thereby avoid any twisting of the material which might be due to the fact that it was fed by a portion only. In cases where it is desired to coat only a portion of a shoe part, for instance, the construction of my machine has special advantages.

If it should be desired at any time to clean the paste applying and feeding elements, the pin 20 is withdrawn from engagement with the lug 19, the cover 13 removed, and the bearing piece and mechanism supported thereby is revolved on thc cone-pointed screws 16 as a center until the elements are nearly in a vertical position and all the parts out of the reservoir are accessible.

Itis to be observed that my machine is of extreme simplicity both in construction and operation. In addition it is of such form of construction that the material being treated is absolutely protected from injury from dirt or adhesive. The right side of the material is always uppermost as it passes through the machine and is engaged by the peripheries only of the feed wheels. These are arranged in a staggered relation with the paste or Aadhesive applying disks and therefore are not liable to take on the adhesive from the latter.

It is to be understood that my invention is not to be limited to the precise constructioiherein shown and described, as it may be embodied in many other forms within the purview of my invention. Therefore I desire to claim the invention broadly except where specifically limited in the following claims.
